What is the rule(or intuition) during chosing parameters during Canny edge detection?

10 October 2017 0 10K Report

Is there any generalized solution for choosing right size of Gaussian filter size and threshold during canny edge detection (for example in case of an automated system that chooses right parameters based on the input image)?
